VALVE.

SPECIFICATION forming part of Letters Patent No. 573,607, dated December22, 1896.

Application filed May 27, 1893. Serial No. 475,689. (No model.)

To @ZZ whom t may concern: shown, consist of two cylindrical portions Beit known that I, ARTHUR MARIGHAL, a E2 E2, seated in cylindricalcavities at each subject of the King of Belgium, residing in end of theslot C and connected by a seg- Philadelphia, in the county ofPhiladelphia, ment-like bar E', which constitutes the valve 55 5 in theState of Pennsylvania, have invented proper.

a certain new and useful Improvement in E3 indicates a valve-rodextending out from Valves, of which the following is a true and one endof the valve E and, as shown in Fig. exact description, reference beinghad to the 3, extending through a stuffing-box K, situdrawings whichaccompany this and which ated in a cast flange J. 6o 1o form a part ofthe specification. The form of the valve-seat D should be Hy inventionrelates to a novel construcsuch as will provide a cavity ofsubstantially tion of valves especially, although not exthe same size asthe segmental bar E of the clusively, adapted for use withblowing-envalve on one side of the slot C, so that when gines orcompressors. the valve is turned to open the slot C the 15 Rotaryoroscillatory valveshave heretofore passage through said slot will beuninterbeen extensively used and in some cases aprupted and of uniformsection. It is also adplied to blowing-engines. 'Such valves havevisable, especially when my valve is used for well-recognized merits,but especially in cases a blowing-engine or pump, that the valve wherelarge volumes of fluid are passed when closed should seat itself on theside of 7o zo through them they are subject to certain the valve-seatthrough which the fluid enters well-recognized drawbacks. the cavity ofthe valve-seat. Thus in the The object of my invention is to provide aupper part of Fig. l it will be observed that valve system which willhave the good feathe valve when closed seats itself on the uptures ofthe rotary valves heretofore used and per part of the valve-cavity, asshown in the 25 in addition additional meritorious features drawings, orouter part relatively to the cyldue to my novel construction, the natureof inder. As a result of this when air is comwhich will be bestunderstood as described in pressed in the cylinder the valve ispresseflav connection with the drawings, in whichtightly to its seat,while when the pressure /PPW Figure lis a longitudinal section throughin the cylinder falls below the atmosphere 8o 3o the cylinder or tub ofa blowing-engine, the there is a tendency to lift the valve from itsupper part being taken through an admisseat. On the same principle,also, the valve sion-valve and the lower part througha delivshown at thelower part of Fig. l, which is ery-valve. Fig. 2 shows, on an enlargedscale, the delivery-valve, is made to seat itself on a portion of theadmission-valve, the secthe inner portion of the valve-seat, or upper 35 tion being the same as in Fig. 1.

In thedrawroo 5o valves, one of which is situated in each cyings I have showneach valve of the series as lindrical valve -seat D. These valves, asconnected by means of independent leverarms F F, &c., with atransversely-extending bar G, which in turn is connected by aconnecting-rod H With the arm I of a lever I I', pivoted at I2, and towhich motion can be imparted at proper intervals by any desiredmechanism.

It is desirable that each rotary valve should be so connected with thevalve actuating` mechanism that it can be disconnected at will, not onlyto permit the :ready repair of each valve, but also so that in case ofinjury it can be left in a closed position while the other valves of theseries are kept in operation. As shown, the lever-arms F are eachdetachable from the valve-rods E3 and the pins g of the bar G. Thus, asshown in Fig. et, the lever F has a hole f at one end, which slips overthe end of rod E3, While ahole f at its other end slips over the pin g.The lever is rmly secured to rod E3 in any convenient Way, as by aset-screw J, While of course it is free to turn on pin g.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In combination with a cylinder, a head B having formed in it a seriesof slots C forming a gridvalve opening, and a series of valve-seats D,one situated in each slot C, a

series of rotary valves E secured in the respective seats D, and meansfor simultaneously operating said valves to open or close the slots.

2. In combination with a cylinder, a head B having formed in it a seriesof slots C forming a grid-valve opening, and a series of valve-seats D,one situated in each slot C, a series of rotary valves E secured in therespective seats D, reciprocating mechanism, as bar G, forsimultaneously actuating said valves, and a series of independentdetachable devices as rods F for connecting the separate valves with thesaid reciprocating mechanism.

3. In a blowing-engine or compressor, the combination with acylinder-headv B having a series of slots G forming a grid-valveopening, and a series of valve-seats C one situated in each slot, aseries of rotary valves E one secured in each slot and arranged to seatthemselves across the slot on that side of the seat through which theair or gas enters the cavity of the valve-seat, and means forsimultaneously actuating said valves.
